Fedora 42 KDE Plasma, admin user can't lock screen

HI folks, I came from Ubuntu, so I not really familiar with KDE and I have strange issue, on my main admin user, it can’t lock screen.
When I close my laptop lid, and open it it won’t lock. Even if I directly press “Lock” button on start menu it do nothing.
It only lock system when I reboot, or sign out.
I tried create new user, not admin, and on it lock screen works properly.
Is it normal behaviour for KDE ?)

I want to use admin account but, with ability to lock my machine when it’s idle or lid closed.
Maybe someone solved this before ?
